Provides explicit makefile targets for files

[madrob]

fixes #165

init depends on vminitd/bin/vminitd, vminitd/bin/vmexec, and bin/cctl
integration depends on bin/containerization-integration
bin/* get generated via make containerization

I like the simplicity of this. I'm a bit concerned that it's harder to follow/reason about.

[madrob]

Are there specific sections that you think are more difficult to understand? We can add some comments there.

I'm not sure what level of familiarity I can expect from folks reading the Makefile, but if the people who expect to maintain it don't understand what's going on then that's probably a good signal that we need more explanation.

@madrob I think the changes to make it more clear what binaries are being built helps a lot! Thanks!

[madrob]

I think this might have a problem where somebody running make containerization won't get an updated bin/cctl by default now. Will need to think about how to deal with this.

@madrob Could they not just run all? That reminds me we also probably want to update the CI workflows

What would you update? It looks fine to me, the problem was that I was trying to build stuff and not paying attention to the CI workflows as an example of the correct way to do things.

@madrob I would change this step make containerization and docs to call make all which includes init, so then we can get rid of building init here

Do you want all to also make docs? (It does not currently.)

It looks like init currently runs with the 6.2 swift snapshot installed by swiftly, which I think is related to #119 and #94 - I don't want to accidentally regress on that.

@madrob Fair enough, let's hold off on those changes then.
